  sorry for the late answer.

I am against abbreviations in option names as much as possible unless it
is a widely accepted term (like PLAB or LAB). Abbreviations obscure the
function when they are acting as documentation, and it is annoying to me
everytime I am not getting it right. (Like "Pct" in "WasteHeapPct").

So I am in favor of not abbreviating it to "HObject", and keeping the
current suggestions.

It is unfortunate that the term "Humongous Object" has been chosen for
G1 instead of the (imo) much more common "Large Object" that would also
be shorter to write. ;)

Thanks for your input,
  Thomas
